Comment on How come LED Light Bulbs only last for about 2-3 Years?

Lights like this:
Have PCBs with LEDs surface mounted to them. This means that the on-off cycle of the bulb causes heat deformation cycles of the PCB. This stresses the foils in the PCB and can eventually cause them to lose connection. That’s why they’ll often start flickering or lose the ability to be cool white, warm white, or specific colors (the different kinds of LEDs in them).
But lights like this:
Use LEDs that aren’t mounted to the PCBs, and will probably last much longer.

Are you sure? Doesn’t the “smart edison bulb” design make it harder to dissipate heat to the casing, therefore making the LEDs get hotter compared to PCBs with LEDs surface mounted on them?
Anyway, if you want your
light bulbsany technology to last long, don’t buy the “smart” variant. “Smart” usually means more components and/or more dependencies on interfaces, and more complexity, so a higher chance to fail.TheRealKuni@lemmy.world 4 days ago
Technology Connections seems to think they’re better and last longer, and I trust him implicitly.
